Security Vulnerabilities - CVEs Published In June 2025
In the Linux kernel, the following vulnerability has been resolved:
ASoC: SOF: Intel: hda-ipc: Do not process IPC reply before firmware boot
It is not yet clear, but it is possible to create a firmware so broken
that it will send a reply message before a FW_READY message (it is not
yet clear if FW_READY will arrive later).
Since the reply_data is allocated only after the FW_READY message, this
will lead to a NULL pointer dereference if not filtered out.
The issue was reported with IPC4 firmware but the same condition is present
for IPC3.

In the Linux kernel, the following vulnerability has been resolved:
mips: cavium-octeon: Fix missing of_node_put() in octeon2_usb_clocks_start
We should call of_node_put() for the reference 'uctl_node' returned by
of_get_parent() which will increase the refcount. Otherwise, there will
be a refcount leak bug.

In the Linux kernel, the following vulnerability has been resolved:
net/mlx5: LAG, fix logic over MLX5_LAG_FLAG_NDEVS_READY
Only set MLX5_LAG_FLAG_NDEVS_READY if both netdevices are registered.
Doing so guarantees that both ldev->pf[MLX5_LAG_P0].dev and
ldev->pf[MLX5_LAG_P1].dev have valid pointers when
MLX5_LAG_FLAG_NDEVS_READY is set.
The core issue is asymmetry in setting MLX5_LAG_FLAG_NDEVS_READY and
clearing it. Setting it is done wrongly when both
ldev->pf[MLX5_LAG_P0].dev and ldev->pf[MLX5_LAG_P1].dev are set;
clearing it is done right when either of ldev->pf[i].netdev is cleared.
Consider the following scenario:
1. PF0 loads and sets ldev->pf[MLX5_LAG_P0].dev to a valid pointer
2. PF1 loads and sets both ldev->pf[MLX5_LAG_P1].dev and
ldev->pf[MLX5_LAG_P1].netdev with valid pointers. This results in
MLX5_LAG_FLAG_NDEVS_READY is set.
3. PF0 is unloaded before setting dev->pf[MLX5_LAG_P0].netdev.
MLX5_LAG_FLAG_NDEVS_READY remains set.
Further execution of mlx5_do_bond() will result in null pointer
dereference when calling mlx5_lag_is_multipath()
This patch fixes the following call trace actually encountered:

In the Linux kernel, the following vulnerability has been resolved:
ice: xsk: prohibit usage of non-balanced queue id
Fix the following scenario:
1. ethtool -L $IFACE rx 8 tx 96
2. xdpsock -q 10 -t -z
Above refers to a case where user would like to attach XSK socket in
txonly mode at a queue id that does not have a corresponding Rx queue.
At this moment ice's XSK logic is tightly bound to act on a "queue pair",
e.g. both Tx and Rx queues at a given queue id are disabled/enabled and
both of them will get XSK pool assigned, which is broken for the presented
queue configuration. This results in the splat included at the bottom,
which is basically an OOB access to Rx ring array.
To fix this, allow using the ids only in scope of "combined" queues
reported by ethtool. However, logic should be rewritten to allow such
configurations later on, which would end up as a complete rewrite of the
control path, so let us go with this temporary fix.

In the Linux kernel, the following vulnerability has been resolved:
xfrm: policy: fix metadata dst->dev xmit null pointer dereference
When we try to transmit an skb with metadata_dst attached (i.e. dst->dev
== NULL) through xfrm interface we can hit a null pointer dereference[1]
in xfrmi_xmit2() -> xfrm_lookup_with_ifid() due to the check for a
loopback skb device when there's no policy which dereferences dst->dev
unconditionally. Not having dst->dev can be interepreted as it not being
a loopback device, so just add a check for a null dst_orig->dev.
With this fix xfrm interface's Tx error counters go up as usual.

In the Linux kernel, the following vulnerability has been resolved:
nfc: pn533: Fix use-after-free bugs caused by pn532_cmd_timeout
When the pn532 uart device is detaching, the pn532_uart_remove()
is called. But there are no functions in pn532_uart_remove() that
could delete the cmd_timeout timer, which will cause use-after-free
bugs. The process is shown below:
(thread 1) | (thread 2)
| pn532_uart_send_frame
pn532_uart_remove | mod_timer(&pn532->cmd_timeout,...)
... | (wait a time)
kfree(pn532) //FREE | pn532_cmd_timeout
| pn532_uart_send_frame
| pn532->... //USE
This patch adds del_timer_sync() in pn532_uart_remove() in order to
prevent the use-after-free bugs. What's more, the pn53x_unregister_nfc()
is well synchronized, it sets nfc_dev->shutting_down to true and there
are no syscalls could restart the cmd_timeout timer.

NFSv4.2 fix problems with __nfs42_ssc_open
A destination server while doing a COPY shouldn't accept using the
passed in filehandle if its not a regular filehandle.
If alloc_file_pseudo() has failed, we need to decrement a reference
on the newly created inode, otherwise it leaks.

In the Linux kernel, the following vulnerability has been resolved:
xfrm: fix refcount leak in __xfrm_policy_check()
The issue happens on an error path in __xfrm_policy_check(). When the
fetching process of the object `pols[1]` fails, the function simply
returns 0, forgetting to decrement the reference count of `pols[0]`,
which is incremented earlier by either xfrm_sk_policy_lookup() or
xfrm_policy_lookup(). This may result in memory leaks.
Fix it by decreasing the reference count of `pols[0]` in that path.

4. Kill execsnoop, when __disable_kprobe() calls disarm_kprobe() for the
disabled kprobe and hits the WARN_ONCE() in __disarm_kprobe_ftrace().
# fg
/usr/share/bcc/tools/execsnoop
^C
Actually, WARN_ONCE() is fired twice, and __unregister_kprobe_top() misses
some cleanups and leaves the aggregated kprobe in the hash table. Then,
__unregister_trace_kprobe() initialises tk->rp.kp.list and creates an
infinite loop like this.
aggregated kprobe.list -> kprobe.list -.
^ |
'.__.'
In this situation, these commands fall into the infinite loop and result
in RCU stall or soft lockup.
cat /sys/kernel/debug/kprobes/list : show_kprobe_addr() enters into the
infinite loop with RCU.
/usr/share/bcc/tools/execsnoop : warn_kprobe_rereg() holds kprobe_mutex,
and __get_valid_kprobe() is stuck in
the loop.
To avoid the issue, make sure we don't call disarm_kprobe() for disabled
kprobes.
